About the author

Thomas Young (1773–1829) was an English physician, physicist, and Egyptologist born in Milverton, Somerset. Raised in a Quaker family, he showed an extraordinary talent for languages and scholarship from an early age, eventually studying medicine in London, Edinburgh, and Göttingen before establishing a medical practice in London.

Young made important contributions to physical optics, helping establish the wave theory of light and demonstrating the phenomenon of interference. His work also influenced the study of elasticity, vision, sound, physiology, and energy; the term “Young’s modulus” commemorates his research into the stiffness of materials.

He also studied ancient languages and played a role in deciphering Egyptian hieroglyphs through his work on the Rosetta Stone. A member of the Royal Society and a respected scientific writer, Young died in London on May 10, 1829.
